NWA1121-NI User’s Guide
109
Server Access Select the interface(s) through which a computer may access the NWA1121-NI using
SNMP and to which the IP and MAC filtering rules you specified below are applied.
Otherwise, select Disable to allow any computer to access the NWA1121-NI through
any interface using SNMP.
Secured Client IP
Address
A secured client is a “trusted” computer that is allowed to communicate with the
NWA1121-NI using this service.
Select All to allow any computer to access the NWA1121-NI using this service.
Choose Selected to just allow the computer with the IP address that you specify to
access the NWA1121-NI using this service.
Secured Client MAC
Address
Select All to allow any computer to access the NWA1121-NI using this service.
Choose Selected to just allow the computer with the MAC address that you specify to
access the NWA1121-NI using this service.
SNMP Configuration
Protocol Version Select the SNMP version for the NWA1121-NI, which you allow the SNMP manager to
use to access the NWA1121-NI.
The SNMP version on the NWA1121-NI must match the version on the SNMP manager.
Get Community Enter the Get Community, which is the password for the incoming Get and GetNext
requests from the management station.
Set Community Enter the Set community, which is the password for incoming Set requests from the
management station.
Trap Community Type the trap community, which is the password sent with each trap to the SNMP
manager.
Trap Destination Type the IP address of the station to send your SNMP traps to.
SNMPv3 Admin
Settings
SNMPv3 Admin Select the check box to enable the SNMP administrator account for authentication with
SNMP managers using SNMP v3.
User Name Specify the user name of the SNMP administrator account.
Password Enter the password for SNMP administrator authentication.
Confirm Password Retype the password for confirmation.
Access Type Specify the SNMP administrator’s access rights to MIBs.
Read/Write - The SNMP administrator has read and write rights, meaning that the
user can create and edit the MIBs on the NWA1121-NI.
Read Only - The SNMP administrator has read rights only, meaning the user can collect
information from the NWA1121-NI.
Authentication
Protocol
Select an authentication algorithm used for SNMP communication with the SNMP
administrator.
MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used
to authenticate SNMP data. SHA authentication is generally considered stronger than
MD5, but is slower.
Privacy Protocol Specify the encryption method used for SNMP communication with the SNMP
administrator.
DES - Data Encryption Standard is a widely used (but breakable) method of data
encryption. It applies a 56-bit key to each 64-bit block of data.
AES - Advanced Encryption Standard is another method for data encryption that also
uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
